No internet when I connect WAN

[Priery]

I bought an ASUS router and want to use my vmg3925-b10b from zyxel as a modem, i connect the asus router to the modem through WAN but then the internet indication light on the vmg3925-b10b goes from green to red.

To my understanding you need to call your ISP. They need to upload a configuration file to your router. Right now it has no Public IP.

Has the modem already been programmed by your ISP? Most ISPs require the modem be programmed by them or else it will not work. Routers can easily be set up by the user with no help from the ISP, the big issue is the modem.

From what I understand a modem that has no router functionality (though this one looks like it does) doesn't need setup from the ISP. A standalone modem simply being a bridge between DSL/Coax/Fiber to Ethernet doesn't get configured. The WAN interface on the consumers router will hold their public IP's, those IP's Default Gateways on the ISP network, DNS servers, etc. So the router needs to be configured. However in this case for the WAN the client cannot configure this themselves. The router needs to have a config file uploaded to it by the ISP.

 

At least I believe that's how that works. In the instance you have an ISP where the modem/router/AP are all build into one box it would be easy to think the modem is what is getting configured when it's really the router.

I've done networking in my area for the last couple years setting up Ubiquiti equipment for residential and business and every single modem I've installed which have all been standalone have had to be programmed by the ISP. I've never had to have the router itself programmed by the ISP it's always been the modem. The modem has to be programmed with you ISP information and the MAC address of the modem have to be registered to your account.

This is correct.  Also once the modem is programmed, it should assign an IP to your wan port since most modems usually distribute ip's via DHCP.

Wait a minute. Are you not using the ISP modem? Thats just a regular zyxel wifi router and it will not work as a modem. You need to get a "Modem" that is compatible with your ISP.

I am using the modem the ISP gave me when I had my internet set up. So I guess Ill just have to contact them tomorrow then, thank you guys

You have to connect a cable from the WAN port on the ASUS router to one of the LAN ports on the Zyxel.

Do I set both ADSL and VDSL to routing?

thank you selle  sorry guys im retarded x)
